To avoid passing on new mutations to offspring, plants may minimize the number of divisions by the stem cells that make flowers and seeds.

The computer vision scientist Greg Johnson is building systems that can recognize organelles on sight and show the dynamics of living cells more clearly than microscopy can.

Theories about how animals became multicellular are shifting as researchers find greater complexity in our single-celled ancestors.

By studying a swarm of flying midges as though it were a fluid, physicists have learned how collective behaviors might stabilize a group against environmental disruptions.

The discovery that apparently dead cells can sometimes resurrect themselves has researchers exploring how far they can push the point of no return.

Researchers struggle to incorporate ongoing evolutionary discoveries into an animal classification scheme older than Darwin.

Contrary to popular belief, bacteria have organelles too. Scientists are now studying them for insights into how complex cells evolved.

New experimental results simultaneously advance and challenge the theory that the brain’s network of neurons balances on the knife-edge between two phases.

Immunologists confirm an old hunch: T-cells identify what belongs in the body by timing how long they can bind to it.
